Note: This is not compatible with current assembler, wait for upcoming commits * Now also supports Linux (CMake) and Visual Studio 2010, see README for build and use instructions * Uses libmpq for now, since at project start stormlib did not work properly on 64bit linux. * Should be a lot faster, a few badly written lines ate most CPU time for nothing... Special thanks to arrai and faramir118 for additional code and fixes
